Question

In an experiment, a student suspends a 950-g weight using a long spring mounted vertically to a lab stand, causing the spring to stretch as much as 12 cm after reaching equilibrium (at rest). She then pulls the weight at equilibrium position down for 8 cm and let go to set it into oscillation. Assuming this is an ideal system such that there is no loss (leaking) in energy such that the spring will oscillate forever. What is the maximum speed of the mass during the oscillation? Express answer in cm and time.
Gravity=9.81
